Arctic Submarine Sonar Ice Draft Profiles and Statistics

Submarine upward looking sonar data provides sea ice draft profiles and derived statistics for the Arctic Ocean. The dataset includes measurements from both U.S. Navy and Royal Navy submarines, covering ice draft characteristics, keels, level ice, leads, and deformed ice. It is produced by the National Aeronautics and Space Administration.

Use Cases

• Analyzing ice draft profiles to measure sea ice thickness over time.
• Calculating statistics on keel dimensions to study ice deformation and ridging.
• Identifying leads and level ice areas to understand ice cover variability.
• Comparing data from U.S. and Royal Navy submarines for spatial coverage assessment.

Strengths

• Data sourced from multiple military submarines, providing unique under-ice measurements.
• Includes both raw profile data and pre-calculated statistical summaries for analysis.
• Cross-platform presence on Data.gov and NASA Earthdata indicates established importance.

Limitations

• Specific row counts, file sizes, and column names are not provided by any source.
• Conflicting last updated dates: Data.gov shows 2026-03 -12 (likely a placeholder), while NASA Earthdata shows 2005-11-30.
• License is listed as 'other-license-specified' on Data.gov but is null on NASA Earthdata.
